@ -87,6 +87,14 @@ Win32-MinGW - ChibiOS/RT simulator and demo into a WIN32 process,
WORKING_AREA(), THD_WA_SIZE() and STACK_ALIGN() instead.
- CHANGE: Renamed the default idle thread function from _IdleThread() to
_idle().
- Added to the LPC2148 and STM32 load scripts the options "ALIGN(16)
SUBALIGN(16)" to the flash loading section in order to enforce the alignment
for both the code and read only data. This is done in order to obtain more
accurate timings from benchmarks, those families have 16 bytes
prefetch buffers and are very sensitive to alignment changes.
You can remove those options in order to save some flash space if accurate
response time is not on top of your priorities, it mainly depends on your
requirements.
*** 0.8.1 ***
- FIX: Fixed a regression in version 0.8.0, the configuration switch
